In a survey on attitudes toward skipping class given to 75 undergraduates at a prominent state university in the Midwest, 84% of 38 respondents answered that they have been or may be inclined to skip a class because of reasons associated with "health": they are tired or just not feeling well. All women (n=20) chose this option, while only 67% of the men did. Beyond gender lines, college year also influenced answers: While 50% of juniors and seniors chose "weather" as a reason to skip class, only 20% of first-year students and sophomores did so. These results suggest that instructors should consider the gender and college-year compositions of their classes as they determine attendance policies or decide whether to offer incentives (e.g., credit, bonus points, or pop quizzes) in their attempts to reduce truancy.
